In the near future , some source energy like coal,oil or fossil fuel will be exhausted. So , there must have another source of energy for people to live . Now , a lot of scientists think about using three kinds of energy: Solar energy , water energy and water energy . In three kinds , people usually prefer solar energy than others . In my opinion , I'll will talk about advantages and also disadvantages of solar energy.
Firstly , solar energy is from the sun . It often rises about twelve hours a day so it's also convenient to use all day
Secondly , when you need a hot bath , just turn on the solar panel on the roof because it's absorb solar energy during the daylight time. Then enjoy it.
Finally , It's minimize the Carbon Dioxide , Sulfur Dioxide and other hamful gases from factories . It's also reduce waste of coal , oil , fossil fuel.
But it's expensive to buy a solar panel because it's exchange a lot of rare meatal like potassium , aluminum or berium.And if you don't use hot water after two - three hours , it will be cooler because it don't have any sun during the night time.
In conclusion , I think solar energy have more advantages than disvantages
